When you're in the Serengeti, especially during the migration, zebra are everywhere. There are so many that you almost become accustomed to their ubiquity as one does seeing pets at a park. I imagine, they become accustomed to safari goers driving by daily. It was great to learn about the collaboration between zebra and wildebeest because one group has a keen sense of smell and the other, keen eyesight. Together, they warn each other of the ever present predators that stalk them constantly.
